WebMay 24, 2014 · Hasse invariants for Hilbert modular varieties E. Goren Mathematics 2001 AbstractGiven a totally real fieldL of degreeg, we constructg Hasse invariants on Hilbert modular varieties in characteristicp and characterize their divisors. We show that these divisors give the… 49 WebHasse invariants is the reduction of an Eisenstein series of weight p - 1. 0. Introduction Moduli spaces of abelian varieties possess a rich geometric structure coming from the reflection of properties of the abelian varieties by the moduli points that parameterize them. This is even more so in positive characteristic where, beside ...

WebJul 1, 2024 · The main idea is to compute a lift of the Hasse invariant (modulo the polynomial f ∈ F q [x] to be factored) with respect to a random Drinfeld module ϕ with … WebFinally, in Section 6, we prove that the Hasse invariant h has no repeated factors. (The authors are unsure if this was a known result. In any event, a new proof is given.) Although this is of independent interest, it also has an application to the formulas for the A iand B i coming from the j-invariant construction: let h def= h a a(h) b b(h)
WebCertain invariants of a quadratic form can be regarded as functions on Witt classes. We have seen that dimension mod 2 is a function on classes: the discriminantis also well-defined. The Hasse invariant of a quadratic formis again a well-defined function on Witt classes with values in the Brauer groupof the field of definition.

WebHasse invariant becomes a (p−1)st power after a field extension of degree (p−1)/2 it was a square to begin with, and the j-invariant is unchanged by field extensions. Finally, this … WebNov 1, 1976 · The Hasse invariant at p is nonzero by Proposition 3.1. The endomorphism ring of C over ZL/p7L is 7L[f]. If Fp denotes the Frobenius at p, then Fp is a root of the characteristic polynomial X2 - fpX -}- p and FD E7L[e].

In Proposition5.10we also prove a special property of the Hasse invariant of a supersingular elliptic curve in Montgomery form - namely, it splits completely over F p2. chinchilla cemetery indexWebtoday are called Hasse invariants; thereby the structure of the Brauer group of an algebraic number eld is determined. (This was elaborated in Hasse’s subsequent paper [Has:1933] which was dedicated to Emmy Noether on the occasion of her 50th birthday on March 23, 1932.) The splitting elds of a division algebra can be explicitly described by chinchilla c and kWebThe classical Hasse invariant satisfies the following four properties: (Ha1) The non-vanishing locus of H is the ordinary locus of sh, namely the locus of points where the underlying abelian variety is ordinary. (Ha2) The construction of H is compatible with varying the prime-to-p level. chinchilla cats for saleWebThe Hasse invariant h p of an elliptic curve y2 = f(x) = x3 + ax + b over F p is the coefficient of xp 1 in the polynomial f(x)(p 1)=2. We have h p t p mod p, which uniquely determines t p for p > 13. Na¨ıve approach: iteratively compute f;f2;f3;:::;f(N 1)=2 in Z[x] and reduce the xp 1 coefficient of f(x)(p 1)=2 mod p for each prime p N. chinchilla can\u0027t get wet
